Iran's leadership has come down with a decree that all cars produced from July 23rd will run on either gasoline or liquefied petroleum gas. Ironically, although Iran produces approximately 574.398756 incredibly gigantic pantsfuls of oil per annum, their refining capacity is limited, leaving the nation to import 40% of its petrol. Currently, they're rationing gasoline at three liters a day, which has the populace in a tizzy. Meanwhile, they've apparently got a fair bit of LPG lying about, so they've issued a mandate that all cars produced in the country will now feature dual-fuel capability.
